Ryota Sakamoto is an unemployed 22-year-old who lives at home with his mother. He spends his days playing an online game called BTOOOM!, and he's one of the top-ranking players in the game. Ryota's mother keeps trying to get him to apply for jobs, but he's told her over the past two years that there's only one job that he wants.

One day, Ryota wakes up and finds himself in the jungle, attached to a parachute. He has no memory of how he got there, and all he has on him are his backpack with a couple of items he bought at a convenience store, a change of clothes, and a pack that he doesn't recognize. When he investigates the pack, he discovers there are bombs inside. After this discovery, Ryota is suddenly attacked by someone else who also has bombs. By the end of the first episode, Ryota comes to discover that he is in a real-life version of the BTOOOM! game.

When I first saw what the premise of the show was, I was afraid it was going to be like Summer 2012's The Ambition of Oda Nobuna. Luckily, Ryota ends up in a real-life version of the game instead of mysteriously ending up in the game itself. Also, I have to give BTOOOM! some credit for establishing the game first instead of simply starting the story with him already in the real-life version of the game.

Visually, there were a couple of shots in the opening and ending credits with some hinted at female nudity. Also, right near the end of the first episode, there's a scene where a female character has a shirt open; however, she's wearing a bra, so not a whole lot can be seen. There were also one or two shots in the episode where blood could be seen onscreen.

BTOOOM! doesn't seem to be too bad of a series for the audience that it's aiming for. While I may not feel a need to watch more of this series right away, I wouldn't be adverse to watching more episodes at some point in the future.

After watching the first episode, I would personally recommend BTOOOM! to anime viewers who are 15 or 16 years of age and older.
